Question

Lightning produces a maximum air temperature on the order
of1.1 x 104 K,while a nuclear explosion
produces a temperature on the order of9.3 c
106 K.Use Wien's displacement law to calculate
the wavelength of thethermally produced photons radiated with
greatest intensity by eachof these sources. Select the part of the
electromagnetic spectrumwhere you would expect each to radiate most
strongly.

(a) lightningλmax = 1nm
It radiates most strongly in the 2 part of the spectrum.

(b) nuclear explosionλmax = 3pm
It radiates most strongly in the 4 part of the spectrum.
